Procedure

To a solution of tert-butyl (6-(3-((tetrahydro-2H-pyran-2-yloxy)methyl)isoxazol-5-yl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methylcarbamate (4.73 g, 11.0 mmol) in dichloromethane (50 mL) was added trifluoroacetic acid (16.9 ml, 220 mmol). The mixture was stirred at room temperature for one hour, then was concentrated, taken up in 2.0 M ammonia in methanol and purified by MPLC chromatography (eluted with 0-10% (1:10:90 NH4OH:MeOH:DCM) in DCM) to yield the product as a tan solid. MS m/z=246.9 [M+1]+. Calc'd for C10H10N6O2: 246.1.
